Decoding the cellular basis of floral fragrance

By Isabel Botany, News

Researchers have created the first single-cell gene expression map of Prunus mume petals. Using advanced RNA sequencing, they identified six cell types driving floral scent production, pinpointing key genes like PmBAHD3. This breakthrough enhances understanding of fragrance biosynthesis, offering potential…

Researchers find trees acclimate to changing temperatures

By Isabel Botany, News, Plant Science

Researchers studied how paper birch trees adapt to climate change by analyzing photorespiration, a critical metabolic process. They found that trees maintain excess enzyme capacity, providing a buffer to environmental shifts. This resilience offers hope for forests under changing climate…

Secrets of the Corpse Flower Revealed

By Isabel Botany, News, Plant Science

The corpse flower’s rare, short-lived blooms emit a pungent scent to attract pollinators, fueled by heat from its spadix. Researchers uncovered genes driving heat and odor production, linking sulfur metabolism and amino acids like methionine and putrescine to its smell.…

Adaptability of trees persists after millions of years of climate change

By Isabel Botany, Climate change, News

Ice age cycles had minimal impact on the genetic diversity of European trees, finds a new study. High diversity arose from traits like long lifespans and pollen traveling vast distances. This resilience offers hope for forests adapting to today’s rapid…

Digitally cataloguing archived plant specimens can transform conservation efforts

By Isabel Botany, News, Plant Science

Researchers emphasize the crucial role of herbarium collections in supporting biodiversity conservation. They advocate for increased funding to herbaria, which face financial threats, citing their effectiveness in generating high-quality, unbiased biodiversity data. While citizen science contributes, herbarium specimens provide a…

A tiny new plant species reaffirms the “miraculous” survival of Western Ecuador’s ravished biodiversity

By Isabel Botany, News

A new 5 cm-high plant species discovered in western Ecuador reaffirms the region's surprising biodiversity. Found in a farmer's backyard, this tiny plant, named Amalophyllon miraculum, highlights the importance of preserving small forest fragments. The discovery challenges assumptions of widespread…

Buzzing decline: landscape is losing insect-pollinated plants

By Isabel Botany, News

Research spanning nearly nine decades reveals a decline in insect-pollinated plant species across the Netherlands. Analyzing datasets, scientists highlight the pivotal role of these plants in biodiversity and food security, with 75% of crops reliant on insect pollination. Urgent conservation…

A new sunflower family tree reveals that flower symmetry evolved multiple times independently. Chrysanthemum lavandulifolium, on the upper left, and Artemisia annua, upper right, are closely related species from the same tribe; the former has bilaterally symmetric flowers — the rays — and the latter does not. Rudbeckia hirta, lower left, from the sunflower tribe has bilaterally symmetric flowers, and Eupatorium chinense, lower right, from the Eupatorieae tribe does not; these two tribes are closely related groups. A sunflower, center, shows flowers with bilateral symmetry — the large petal-like flowers in the outer row — and without bilateral symmetry — the small flowers in the inner rows.

New sunflower family tree reveals multiple origins of flower symmetry

By Isabel Botany, News

The sunflower family's intricate evolutionary history, unveiled through genetic analysis, showcases the fascinating phenomenon of convergent evolution. Flower symmetry, a key trait, has independently evolved multiple times within this diverse plant group. Insights gleaned may aid in breeding plants with…

Botanists analyze the role of pollinators in the evolution of flowers with various sexual forms

By Isabel Botany, News

Botanists explore Darwin's theory on precise pollination in flowering plants. Their study reveals correlations between heterostyly, floral traits, and pollinators, supporting Darwin's hypothesis. This macroevolutionary analysis sheds new light on the role of ecology in plant reproductive mechanisms.
